To all whom it may concern:

Be it known that we, HENRY E. PRIDMORE and IVILLIAM R. BAKER, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inHarvesters, (for which Letters Patent of the Kingdom of Great Britain,No. 7,693, were granted, with our knowledge and consent, on the Sth dayof June, 1886,) of which the following is a specification.

An application' was filed iu the Patent Office ot' the United States onthe 10th day of July, lS86,Se1-ial No. 207,666, by ourselves for LettersPatent for an improvement in harvester-frames In such application thesills and girts of the elevator-frame were described as formed of squarepipe, or, in other Words, of tubes of rolled or forged metal,rectangularin cross-section; but the rear platform-sill was retained inthe old and cumbrous wooden form. One feature of the present inventionconsists in constructing this latter sill, and also the divider-girt, ofsquare pipe, and in accessory devices for uniting the divider-girt tothe angle-iron linger-bar and tothe dividerboard, and also forprotectingthe grain-wheel.

A further feature of the invention relates to the tightener for theplatform-apron, and yet other features relate to the mounting of theinner roller of the platform-apron and to the supporting of the rear endof the seatplank over the elevator.

In the drawings, Figure l is a top plan vieuI of a machine embodying ourinvention, the platform-apron being ,removed to expose the tightener.Fig. 2 is a rear elevation of said machine; Fig. 3, an elevation fromthe diyider end; Figs. et and 5, enlarged .details in side and rearelevation, respectively, of the joint between the finger-bar anddivider-girt;

Figs. G, 7 and 8, enlarged details in top planA the joint between thedivider-girt and rearr sill of the platform-frame; Fig. 10, an enlargeddetail of the platform in vertical transating parts of theapron-tightener; Figs. 17, Y

18, and 19, enlarged detailsin plan, cross-section, and side elevationof the bearing-box for the movable apron-roller; Fig. 20, an enlargeddetail in side elevation of the grainwheel bra cket or rack-standardmounted upon the divider-girt; Fig. 2l, a horizontal sectiontherethrough, showing also the grain-wheel on thecorrespondingly-numbered line in the preceding figure; Fig. 22, avertical section, and Fig. 23 a horizontal section, as likewiseindicated by numbered lines; and Fig. 24, a rear elevation thereof.

Now, proceeding to describe the invention, the front sillA of theplatform-frame is or may be a bar of wood, as usual, forming a back toan angle-iron finger-bar A', which has its horizontal Web d uppermostand flush with the upper edge of said sill, and, being bolted thereto atintervals, strengthens and braces it. The front sill is overlaid by awooden strip A2 to close the space beneath the upper ply or surface ofthe platform-apron when this is higher than the finger-bar. The rearsill B, as already intimated, is to-be constructed as a square pipe ortubular bar of rolled orforged iron, rectangular in cross-y section,occupying the Vplace of the customary Wooden rear platform-sill. At itsouter or grain end this sill receives a metal bracket or spacing-blockI3', having slings t) at its foot,whereby it saddles and closelyembraces the upper side of the sill, and at its top a slightly-obliqueseat b for the rear end of the divider-girt C, which likewise is arectangular tubular barand is secured at this point by a bolt c, passingthrough the bracket and rear sill, thence entends forwardly pastthcfinger-bai' and to the point of the divider, being suitably supported.adjacent to the finger-bar by an upright or standard therefrom.

To the inner side of the tubular rear sill, or

or board C2, placed on edge along said ,bot-

torn boards, which supports the rear guidebar c2 for the platform-apron,the front guidebar c3 being secured to the front sill in the usual way.The space between the plank and the rear sill vmay be covered by a lidC3, hinged to said plank, and thus form a toolbox, and this lid may atany time be turned up to act as a shield or wind-board for the rear ofthe apron.

Overlapping the rear sill of the platformframe at its stubble end and onits upper side is the rear sill D of the elevator-frame, also formed asa square pipe or hollow bar of rolled or forged iron rectangular incross-section, and it may be here stated thatall of the sills or girtshereinafter mentioned are of similar form and structure, except that thegirts will ordinarily be of less diameter than the sills.

When a wooden rear sill is used for the platform-frame, itis of suchheight as to come up against the rear elevator-sill and be bolteddirectly thereto, but the tubular sill will be ordinarily low down, andfor a reason presently given it is often necessary to have theelevator-sill considerably higher. Therefore spacing brackets or lifts Dof metal will beV employed between the two sills where they overlap.Two. of these brackets are employed, both having snugs CZ to embrace theplatformsill and seats d for the reception of the ele.- vator-sill,onebeing located at the stubble end of the platform-silland the other atthe inner or grain end of the elevator-sill, and bolts cl2 passingthrough the two sills and brackets complete the joint. The brackets arealso offset at one side to form prolongations cl3 of the seats for theelevator-sill beneath the inner cross-girts of the elevatorframe, thatsaid girts may be bolted through the sills to such oifsets, as presentlyexplained.

As in the before-mentioned application, the front platform-sill and thefinger-bar attached thereto are likewise overlapped by a tubular bar Eof rolled or forged iron, also rcctangu,` lar in cross-section, whichextends therefrom a suthcient distance to constitute the front sill ofthe elevator-frame. The rear elevatorsill is in line with the rearplatformsill; b-ut the front elevator-sill usually iares somewhat fromthe platformsill, to which it is attached through the finger-bar, togive more space for the main wheel and binding attachment.Spacing-brackets are interposed between the front elevator-sill andiinger-bar where they overlap, in order to provide a space for theplayof the sway-bar, Where such bar is located beneath the A-frame ofthe elevator, or to block up the elevator-base frame, which is also thegear-frame, to a higher level than the platform, and this in the presentconstruction is the reason why such brackets are employed between therear sills, as previously stated, although the sway-bar does not or neednot pass between said rear sills, to wit, to bring the rear sill intoits proper relation with the front sill.

F represents chairs such as employed in the Baker and Pridmoreconstruction interposed between the elevator-sills and the crossgirts,of which latter four are shown, the innermost girt G in the angle at thefoot of the elevator, then the two girts H H', constituting the lateralbars of the wheel-frame, and, nally, the outergrtl at the stubble end ofthe machine; but of course the number depends to some extent upon thetype of machine or style of binder to be carried. The angle-ironnger-bar, the front elevator-sill, and the cross-girts are securedtogether in essentially the same way as heretofore; but as the woodenrear platform-sill is now dispensed with and spacing brackets or blocksemployed between the two square 4bar rear sills the rear ends of the twoinner girts are now secured by bolts passing through girt, chair,elevator-sill, and offset from the respective underlying spacing-block,while the sills themselves are united by bolts passing through each andthrough the intermediate block.

The front and rear guides for the platformapron are connected near thedelivery end by a cross-beam K, upon which is fixed a metal bridle K',having guideways 7c for the play of a block K2 lengthwise of theplatform. from this block a spindle 7a passes through the bridgeconnect-ing the two arms of the bridle, and a spring 7a2, coiled aroundthe spindle and`resting at one end against the bridge and at the otheragainst a collar or nut k3, secured to the end of the spindle, tends toconstantly force or draw the block toward the divider. Brace-rods K3,rigidly secured to said block, fiare outward therefrom toward and arerigidly secured to the bearing-boxes ol for the gudgeons ofthe'idle-roller K4 of the platform-apron, and these bearings haveflanges 706, sliding in ways formed in the divider ends of theapron-guides. Thus the idleroller is constantly forced ou tward towardthe divider, keeping the apron taut.

The inner or non-adjustable roller L for the platform -apron has itsrear gudgeon Z supported in a long sleeve-bearing l', that ex- IOO IIO

tends from the vertical plank C2 rearwardly means of an angle-ironbracket M, which sits upon the rear platform-sill at and risesvertically troni the foot of the inner strut, which is herein shown asforming a rear boardto the elevator after being suitably bolted to saidstrut and to the bracket-plate, which secures it to the rear sill, thenextends horizontally a short distance toward the stubble side in ordertoform a seat to receive and support the seat-plank M', then passing ata slight upward incline toward said stubble side, is again bolted to theinner strut, and finally to the outer strut, making a very light andstrong brace and siibserving two functions. y

As practically the whole platform-frame is of metal, it becomesnecessary to modify the means whereby the divider and the grainwheel aresupported. The divider-girt, it has already been explained, extendsobliquely forward, and, as usual, is in a horizontal position. It hasbeen noticed that it is blocked up from the rear sill by means of aspacingbracket. r1 his is not absolutely necessary, but is adopted inorder to raise it above the level of the upper ply of the platform apronor carrier, thus allowing the end of the latter to extend beneath or becarried beneath by the action of the tightener upon its movable roller,so as to exclude the possibility of grain dropping between. It followsof course that the forward end of the girt will be correspondinglyraised above the finger-bar, the provision for which will be directlystated. It is then continued beyond the finger-bar to practically theextreme point of the divideigwhere a shoe N, capping and covering itsopen end, is bolted toit, from which the inclined dividing-board Nextends upwardly, outwardly, and rearwardly. A second or false shoe Nzisbolted to the divider-giri; somewhat to the rear of the divider-shoe,and is formed with a socket 7i, into which the point of the outerguard-fin ger n enters, partly to insure a clean division of the grainand partly to brace the finger-bar and divider-girt.

A metal upright O is bolted to the dividergirt immediately above thefinger-bar and has an offset 0 sitting over said girt and secured by across-bolt to make the connection more certain, and beneath it is bentlaterally and formed with a seat, which rests upon said finger-bar, anda flange o', depending along the vertical flange of said bar andembracingT it by a snug o2 at the bottom, and secured to said flange byhorizontal bolts, while at its upper end it bends obliquely at oi", soas to be secured to and aid in supporting` the dividerboard.

The grain wheel P turns upon a stub-axle p, projecting from a slidingblock p', sliding` in ways in a rack-standard P', and adjusted by meansof a lever P2 and a dog controlled therefrom. Such rack-standard and theaccompanying means of adjustment have been used heretofore upon machinesintroduced into the market by the McCormick Harvesting` Machine Company,with these' exceptions,

that the standard is now bolted to the tubular c injuries, a fender-barR is bolted at r to the` grain end of the rear platform-sill, then isbent outward and carried forward outside of said sill until immediatelyin front of the wheel it reaches the just-mentioned upright, whichconnects the finger-bar, divider-girt, and grain-board, when it passesthrough lateral snugs r', formed integrally with the foot of saidupright at and just above the grain end of the front sill andfinger-bar, thence is bent obliquely inward untilI it reaches the frontend of the divider-girt, to which it is secured, preferably, by the samebolt that unites the latter to the divider-shoe.
